ABSTRACT
Nasoalveolar molding (NAM) can be done effectively to reshape the nasal cartilage and mold the maxillary dentoalveolar arch before surgical cleft lip repair and primary rhinoplasty. Presurgical NAM helps as an adjunct procedure to enhance the esthetic and functional outcome of the surgical procedures. We have developed a modified NAM device to suit to the needs of the patients coming from distant places for the treatment. This device helps in reducing the number of frequent visits the patient needs to take to the craniofacial center. The purpose of this presentation is to report this treatment technique and discuss its application.
ABSTRACT
Stem cells are the most interesting cells in cell biology. They have the potential to evolve as one of the most powerful technologies in the future. The future refers to an age where it will be used extensively in various fields of medical and dental sciences. Researchers have discovered a number of sources from which stem cells can be derived. Craniofacial problems are very common and occur at all ages. Stem cells can be used therapeutically in almost every field of health science. In fact, many procedures will be reformed after stem cells come into play. This article is an insight into the review of the current researches being carried out on stem cells and its use in the field of orthodontics, which is a specialized branch of dentistry. Although the future is uncertain, there is a great possibility that stem cells will be used extensively in almost all major procedures of orthodontics.
ABSTRACT
Cleft size at the time of palate repair might affect the difficulty of surgical repair and, thus, indirectly postoperative maxillary growth. This retrospective study aimed to determine whether a correlation existed between the cleft size at the time of palate repair and the growth of the maxilla. Maxillary dental casts of 39 infants with non-syndromic complete unilateral cleft lip and palate, taken at the time of palate repair, were used to measure cleft size. Cleft size was defined as the percentage of the total palatal area. The later growth of the maxilla was determined using lateral and postero-anterior cephalometric radiographs taken at 9 years of age. The Pearson correlation analysis was used for statistical analysis. The results showed negative correlations between cleft size and the maxillary length (PMP-ANS, PMP-A) and the maxillary protrusion (S-N-ANS, SNA). These data suggest that in patients with complete unilateral cleft lip and palate there is a significant correlation between the cleft size at the time of palate repair and the maxillary length and protrusion. Patients with a large cleft at the time of palate repair have a shorter and more retrusive maxilla than those with a small cleft by the age of 9 years.
